nirs4all-methods
nirs4all-methods is the full numerical/method engine distribution. The Python
distribution name is nirs4all-methods; the import package is n4m, matching
the stable libn4m C ABI and n4m_* exported symbols.
The wheel bundles the libn4m shared library, so pip install nirs4all-methods
is self-contained — no separate native build is required. The slim pls4all
distribution remains available for PLS-focused users; both distributions load
the same ABI family.
import n4m
from n4m.estimators.regression.latent import PLS
print(n4m.version()) # project version + ABI, e.g. "1.0.21+abi.2.6.0"
print(n4m.abi_version()) # ABI triple, e.g. (2, 6, 0)
model = PLS(n_components=2).fit(X, y)
pred = model.predict(X)
n4m loads libn4m via ctypes.CDLL and exposes version/ABI helpers,
Context, and role-based packages such as n4m.estimators, n4m.transform,
n4m.feature_selection, n4m.model_selection, and n4m.augmentation.
Estimator-style wrappers live under those role packages; there is no flat
n4m.sklearn package in the ABI 2 surface.
Native hyperparameter studies can be checkpointed without Python pickles:
checkpoint = optimizer.save() returns portable N4MOPT bytes and
Optimizer.load(checkpoint) resumes the exact sequential ask/tell trajectory.
Set N4M_LIB_PATH to point at a development libn4m build when overriding the
bundled wheel library.
